       | Most commenters here are misunderstanding the paper. This is
       | research on a wireless RF power transfer and low strength
       | magnetic field sensing system for BCI sensors. It is _not_ about
       | BCI sensors itself. This is about wireless power transfer and
       | modulating the reflected signal to broadcast the sensor
       | information. In other words your brain computer interface no
       | longer needs a subdermal battery.

       | What do people make out of the fact that this is an MDPI article
       | but from a reputable group?

       | How does this sensor actually detect brain activity? Lots of
       | details about RFid, etc... but not the actual sensor used in the
       | first place.

       | Also, this should be tagged (PDF)

         | From the lack of details, I can only assume it detects brain
         | activity with future funding/development.
